The Dendera 'Light bulb'

[DPKing]

The (huge) problem here is that none of the seams are leakproof.

The whole structure is riddled with holes because of how badly the blocks fit together.  Even with the mortar.

Not saying it was easy, but I think it is doable, they were able to water proof their ships.
And this also explains why they built these massive structures around these rooms to contain the heat/pressure

The joints look good

Why do you think the architects who explored this pyramid randomly added this pit at the bottom of the shaft?

Obviously, I don't know.

Which part of the diagram is that photo supposed to show?

I don't see how. The photo shows what looks like two surfaces making a concave surface, while the diagram only has convex surfaces.

I updated with the video I clipped it from

But I believe the architects give the best view of it, I guess it wasn't boarded up in the 60s

Thanks, I see it now.

In the frame capture you posted I didn't understand that the horizontal area was made of boards.

"Waterproofing" isn't the same as "being able to take 3000 psi."  Egyptian ships were sewn together (yes, sewn) and pitch or bitumen was used to caulk them.

Pitch can actually be melted in an ordinary fire (or candle flame, for that matter.)

The strongest caulk we have can only take pressures under 50 psi.

In a previous answer, you gave "Giving 42 atm and 538 degrees Celsius, the numbers needed for this reaction"  -- that's roughly 1,000 degrees F and a psi of 617, none of the materials you show can hold up to that kind of action.  Doesn't matter how many blocks you stack on it, it will break the original tunnel/materials and you'll have water everywhere.



Also, while a photo might show that "this joint looks good", you're not seeing the mortar (which would have been blasted out with the first rush of water) and you're only seeing the blocks that fit together nicely.  (I've seen the place in person.)

Would the stone fuse together?  I will ask and see if he has answer for this

The heat would be focused at the top of the air reformers as seen by the staining, the water is creating the pressure

The condition of the chambers thousands of years ago is unknown, but looking at the pictures on this site, joints are remarkable even today

One other point, the staining is heaviest on the south walls(left side in the pics) as the reaction moved through the chambers.

What kind of stone is that, limestone?

Do you know what happens when limestone gets too hot? It turns into quicklime. If those stones are limestone and they used high temperatures (above 600º C) the stones would turn into quicklime and crumble.
And the ammonia would probably react with it too, but was never good at chemistry.
